Pyrevit for revit 2027 does not load

I have downloaded the .exe for for pyrevit 6.4.0.26100. I can’t get it to load into Revit 2027. Is something different this time?

Run pyrevit env in cmd to check if it is attached. 2027 sth should show up under attachments. If not, attach it manually, there’s a help page on notion
